Thank you for the link. Do you have a demo URL where prospective purchasers can see v1 running?
And since you are not selling a licence for v2 could you please explain how ethercrash has an almost identical looking site to bustabit?
I might be off here, but you already have all the information you need. Ethercrash runs the V1 version of bustabit. That should answer both of your questions.
